Last weekend’s event featuring Floyd Mayweather Jr. and Canelo Alvarez had all the appearance of a blockbuster Hollywood summer movie, which is why boxing should be worried, according to THE RING contributing editor Brian Harty.

The Floyd Mayweather-Canelo Alvarez fight totaled more than $2.6 million in closed circuit ticket sales in Las Vegas on Sept 14, setting a new record, according to the Nevada State Athletic Commission.

When Floyd Mayweather Jr. and Canelo Alvarez enter the ring on Saturday, both will do so with undefeated records. It isn’t the first time either has faced a fellow ‘0,’ however. Here’s a look back at those fights.

Carlos Molina has had one of those careers: He’s respected as a fighter’s fighter but has a knack for hard-luck losses. On Saturday against Ishe Smith, though, he’ll finally get his shot at a world title.

British welterweight Ashley Theophane recently made a career-altering decision by signing a long term deal with Mayweather Promotions and, as a result, will face off against Pablo Cesar Cano on the undercard of Floyd Mayweather vs. Canelo Alvarez on Sept. 14.

RingTV’s Dominic Verdin reports from the Mayweather Boxing Club in Las Vegas, where Floyd Mayweather recently held a media day workout for his Sept. 14 showdown with Canelo Alvarez. Verdin spoke to Roger Mayweather and Floyd Sr., who said Alvarez’s trainers and team “look like winos.”

Welterweight contender Marcos Maidana is expected to join his countryman Lucas Matthysse, as well as well as top boxing talent, such as Floyd Mayweather Jr. and Adrien Broner, by signing with manager/advisor Al Haymon on Wednesday.

As he heads into a Sept. 14 clash with IBF beltholder Ishe Smith, junior middleweight Carlos Molina has remained positive over the course of his hard-luck career, saying, “I feel as if everything is happening for a reason.”
